The mortality and suicide rates for involuntarily committed patients in Denmark are presented. Two cohorts of psychiatric patients committed to a mental hospital from January 1, 1971 to December 31, 1975 (8322 people) and January 1, 1981 to December 31, 1985 (5253 people) have been followed. The standard mortality rate (SMR) in relation to the total Danish population were 4.9 (4.5-5.4) and 5.2 (4.7-5.8), respectively, for the two cohorts, during the first year after involuntarily commitment to a mental hospital. During the same period, the SMR for suicide among the committed patients were 44.9 (37.1-53.9) and 30.9 (24.2-38.9), respectively. The crude suicide rates among the committed patients during the first year after the commitment were 14.3 and 14.0, respectively, per 1000 years, unchanged between the cohorts. Short length of stay in hospital (< 14 days), a nonpsychotic main diagnosis, male sex, and age 35 years or more were equally related to high risk of suicide in the 1971 cohort as evaluated to proportional hazard methods (Cox regression), and short length of stay and commitment on the danger indication provided the most information in relation to high suicidal risk in the 1981 cohort. Methodological problems and the reasons for the results are discussed.
本文呈现了丹麦非自愿入院患者的死亡率和自杀率。对两组精神病患者进行了随访，一组是1971年1月1日至1975年12月31日期间入院的（8322人），另一组是1981年1月1日至1985年12月31日期间入院的（5253人）。在非自愿入院精神病院后的第一年，两组患者相对于丹麦总人口的标准死亡率（SMR）分别为4.9（4.5 - 5.4）和5.2（4.7 - 5.8）。同期，入院患者中的自杀标准死亡率分别为44.9（37.1 - 53.9）和30.9（24.2 - 38.9）。入院后第一年，入院患者的粗自杀率分别为每1000人年14.3和14.0，两组之间无变化。根据比例风险方法（Cox回归）评估，住院时间短（<14天）、非精神病性主要诊断、男性以及35岁及以上年龄在1971年队列中与自杀高风险同样相关，而在1981年队列中，住院时间短和基于危险指征的入院提供了与自杀高风险相关的最多信息。本文讨论了方法学问题及结果产生的原因。
